Decision: 5x4 (SBP) or 5x4.5?

I wont speak on the bbp vs sbp as most of the guys here have it covered. I would like to bring up the scarebird kit. It uses off the shelf toyota and gm parts at a fraction of the price and doesn't increase track width by anything more than a negligible amount. You can either redrill the rotor to use sbp wheels or redrill your hub and use screw in studs for bbp.

It's cheap and cheerful.
